Abstract Synthesis of 2- epi -fortimicin B has been accomplished by processes involving solvolyses of both 1- N -benzyloxycarbonyl- and 1- N -acetyl-2- O -(methylsulfonyl)fortimicins B, which occur with participation of the carbonyl oxygen atoms of the 1- N -acyl groups. The results illustrate both the greater effectiveness of acetamido groups in neighboring-group participation relative to benzyloxycarbonylamino
